Just as a general pointer, Wings albums are counted as anything after Ram and McCartney (so 1972-1980) and anything up to the Japan tour. I felt it appropriate to clarify this as Paul McCartney has, after this time, released solo albums as just Paul McCartney, although these are not relevant to reviewing Wings'Greatest.
I do like all the tracks on this album and it's good for the very casual listener who likes all the hits and does not want to commit to buying more albums but it's not, in my opinion, Wings' Greatest songs. Or not all of them. I love these songs but there are some very obscure beauties, such as Helen Wheels, Nineteen Hundred And Eighty Five, Picasso's Last Words (Drink To Me), Mrs Vandebilt, Bluebird (and these are just songs from one album; Band On The Run). There are countless other Wings songs which are wonderful and are not conveyed on this album.
I suppose it does what it says on the tin, though. It's Wings Greatest Hits. But it also misses out a lot of great tracks from Venus And Mars. For a better overview of Paul McCartney's Wings work, which does happen to include some solo stuff, try Wingspan; about the same price but a double CD so better value for money. You may even find you like his solo stuff too!!
